Inrush Current
When the power supply switch is first turned
on, an inrush current is generated. Ensure there
is enough power available for the power supply
when first turned on, especially if a number of
units are turned on at the same time.
Capacitive Load
When the power supply connects to a capacitive
load, e.g., capacitor, the load is being charged
consecutively and the larger the voltage change, the
more the current grow. Also, the overshoot will be
possibly generated within the currents output,
therefore leading to output turned off thanks to
overcurrent protection from the power supply.
It is suggested to lower down the set voltage output
from power supply so that the voltage of capacitive
load decreases per certain unit time. In addition, a
block diode is necessary to keep current from
flowing back to the output terminal of power
supply. Refer to the figure below where a block
diode connects with the capacitive load in series to
efficiently prevent current from flowing back to the
power supply.

Inductive Load
When the power supply connects to an inductive
load, e.g., inductor, which generates a back EMF
(Electromotive Force) when output current is
accidentally turned off, a backflow diode is
necessary for absorbing the back EMF, which may
cause irreversible damage to the power supply.
Refer to the following figure where a backflow

Grounded Neutral
Output
Basically, grounded return on the neutral output is
allowed for ASR-3000 series and electric shock may
occur if not following the grounding procedure
based on the local electrical safety codes. In some
cases, 0 V is specifically required between ground
and neutral, which can substantially moderate
ground loops, thus keeping sensitive equipment
from effects of ground loops and reducing ground
noise.
Ground & Neutral
Shortcut
Illustration
CAUTION
Owning to the fact that the neutral has been shortcut
with the ground which is referenced to the chassis
ground, few electric shocks may still take place from
time to time, for which we sincerely ask your
additional attention.
Grounding
The output terminals of the ASR-3000 series are isolated with
respect to the protective grounding terminal. The insulation
capacity of the load, the load cables and other connected devices
must be taken into consideration when connected to the protective
ground or when floating.

Wire Gauge Considerations
56
OPERATION
To minimize noise pickup or radiation, the load
wires and remote sense wires should be twistedpairs of the shortest possible length. Shielding of
the sense leads may be necessary in high noise
environments. Where shielding is used, connect
the shield to the chassis via the rear panel
ground screw. Even if noise is not a concern, the
load and remote sense wires should be twistedpairs to reduce coupling, which might impact
the stability of the power supply. The sense
leads should be separated from the power leads.

IPK Limit is set ON by default.
Background
The IRMS and I settings set the current of the
output. Setting the RMS or AVG current sets a
limit on the current that can be sourced by the
power supply. Once the output current is over
the setting, the output will set to off.
Steps
1. Press Irms to access the IRMS or I
menu depending on varied modes.
Also, it is available to use the scroll
wheel followed by the Enter key to
make the IRMS or I parameter
selectable as well.
2. Set the IRMS/I level with the scroll wheel or
with the F3 ~ F4 soft-keys. The MAX and MIN
soft-keys set the IRMS or I level to the
maximum and minimum, respectively.
Almost identical with the concept of previous IPK
Limit function, the IRMS/I Limit function keeps the
IRMS/I value within the certain limit when the
predefined value is reached. If, on the other hand,
this function is turned off, the output will be
disabled instantly when IRMS/I Limit off level is
reached.
Note
IRMS Limit is set ON by default. The IRMS minimum
value will not be less than 1A.
